Hi all, I'm trying to pinpoint the source of an audio stuttering problem I'm experiencing when using WSJT-X on Big Sur. I know, I should have waited to upgrade, and I'm kicking myself for it. When transmitting, maybe once every half hour or so, the transmit audio sputters and stutters until I end the transmission and restart it. Then, it's fine. I'm using an IC-7300 with the SiLabs driver (which I believe actually isn't used in Big Sur as Apple provide in-house support). I don't know if this is a WSJT-X problem, or an Apple problem, but I am wondering if other people have experienced this. Also, let this serve as a warning for those of you considering upgrading. Fldigi only displays a grey screen as of today, if that matters to you.
